摘要

Abstract Bulky ligands for cleft-type metal complexes were synthesized from thio ketones and diamines in yields varying from 20–80%. A molecular structure determination of one ligand N, N′-bis (12H-benzo [a]-xanthen-12-ylidene)-1, 2-propanediamine (19) was performed. A metallocleft was constructed by a self-assembling process with zinc (II) chloride. A crystallographic study of this zinc complex (24) revealed surprisingly that an ...
